Here I show the vermicomposting system after the addition of a vent to the top of the bottom stackable tray. This is tray one. Tray two will not be added until tray one is about finished.
A vent hole was cut into the top of the tray. This same vent hole will be used as an access hole when tray two is added on top of tray one. This will allow the worms to move up into fresh material as the bottom material becomes exhausted.
The vent plug is a kitchen drain basket and I have it covered with a fine mesh net which is also used for kitchen drains. The opening in the drain basket as large enough to allow oxygen into the system so the worms can breath, and the openings are small enough to both keep the worms in as well as large insects out of the box. The fine mesh net keeps the smallest insects out of the system.
The vent plug is removable allowing easy access to add new food to the system. The lid is also removable.
These styro foam boxes are ubiquitous in Tokyo and they are also an easily recyclable material accepted at most recycling locations such as grocery store drop boxes.
I'm looking for a system that anyone can build themselves, small enough to fit on a small balcony, and scalable enough to serve 1 household.
This is just a work in progress. There are many worm farm systems. Due to the space requirements of hot thermo-composting, a worm bin is about the only option a city dweller has available.
